Viport cardiac stress-measurement device
This device is designed for regularly measuring the state of cardiac health, and for making comparative measurements. The measurements allow us to get feedback about the current state of health.
These measurements are based on the evaluation of the heart rate variability (HRV) parameters by recording an electrocardiogram (ECG). The measurement is carried out on the skin close to the heart, on the left side of the chest, three inches below the collarbone.
To start the reading, simply press a button. The device beeps at the end of the measurement. The device records and analyses the incoming ECG signals. When the measurement is completed, the results appear on the graphic display. The measured stress value (cardio stress index – CSI) is shown numerically on a 0-100 point scale. The device displays the heart rate, the duration of ventricular stimulus phase in milliseconds (QRS), heart rate variability (standard deviation of measured time between individual heartbeats – RRSD) and possible cardiac arrythmias (with YES or NO indication).
Evaluation of the data obtained can be performed independently, easily and quickly.
